The untitled Batman-Superman movie finally has a title. Warner Bros. unveiled the title as Batman v. Superman: Dawn of Justice just as production got underway in Michigan.

Zack Snyder is directing the film, which stars Henry Cavill in the role of Clark Kent/Superman and Ben Affleck as Bruce Wayne/Batman.

"Dawn of Justice" refers to how the movie sets up the Justice League movie, which Snyder and the studio are already developing. That movie could release as soon as 2017.

Dawn of Justice also stars Gal Gadot as Diana Prince/Wonder Woman, Jesse Eisenberg as Lex Luthor, Jeremy Irons as Alfred and Holly Hunter in a role newly created for the film. Amy Adams, Laurence Fishburne and Diane Lane are reprising their roles from Man of Steel. The movie is shooting at the Michigan Motion Picture Studios and on location in and around Detroit. It also will shoot in Illinois, Africa and the South Pacific.

Batman v. Superman: Dawn of Justice is written by Chris Terrio from a screenplay by David S. Goyer. Charles Roven and Deborah Snyder are producing, with Goyer, Benjamin Melniker, Michael E. Uslan, Wesley Coller and Geoff Johns serving as executive producers.

Set to open worldwide on May 6, 2016, Dawn of Justice is based on Superman characters created by Jerry Siegel and Joe Shuster, Batman characters created by Bob Kane and Wonder Woman created by William Moulton Marston, appearing in comic books published by DC Entertainment.
